Washer DIN 2093

Description

High-precision cymbal spring manufactured according to DIN 2093 and designed to work dynamically withstanding a high number of cycles. Its conical shape offers an axial elastic force proportional to the deformation to which it is subjected in the same direction. They can be stacked both in series and in parallel to achieve a larger spring.

Assembly

The assembly is carried out by placing the discs in series for greater deflection and in parallel for greater force. Make sure surfaces are clean and lubricated to prevent wear and tear. Place the discs correctly aligned and avoid overloads that exceed the maximum indicated deflection.

Materials

DIN 2093 saucer springs are mainly made of carbon spring steel (EN 42J, EN 47) with HRC 50-55 hardness, offering high strength and long service life. They can also be produced in stainless steel for corrosive environments. Typical finishes include phosphating for corrosion protection and oiling to reduce friction and wear.

Technical drawing and installation parameters of the DIN 2093 disc springs

This technical diagram defines the dimensions and geometric variables that are essential for the correct selection and installation of the DIN 2093 disc spring, of conical shape and axial spring behaviour. It shows the critical dimensions linked to the specification tables, such as the outside diameter (d1), the inside diameter (d2), the material thickness (S) and the free height of the disc before deflection (h). Complying with these dimensions ensures the intended load curve, allows the discs to be stacked in series or in parallel to adjust travel and force, and guarantees reliable dynamic operation over a high number of cycles.
